SEAS Prestige T18REX/XFC - H1353-08/06 7" Coaxial Woofer

The SEAS Prestige T18REX/XFC - H1353-08/06 7" Coaxial Woofer represents a masterful blend of engineering precision and acoustic refinement, designed to deliver exceptional full-range sound from a single, space-efficient driver. This coaxial driver integrates a dedicated tweeter within the woofer's centre, creating a true point-source configuration that ensures seamless crossover behaviour and coherent soundstage reproduction.

Ideal for high-fidelity audio systems, this driver excels in compact two-way designs where space is at a premium but performance cannot be compromised. It is particularly suited to bookshelf speakers, satellite systems, and custom automotive installations, where its unified driver arrangement simplifies enclosure design while maintaining phase coherence and imaging accuracy. The T18REX/XFC also serves as an excellent upgrade for existing loudspeaker projects seeking refined midbass and treble integration.

Technically, the woofer features a 7-inch (165.1 mm) nominal diameter with a maximum linear excursion of 3 mm, supported by a robust motor system that yields a total Q factor (Qts) of 0.24. The low Qes of 0.29 and Qms of 1.64 indicate a well-damped, controlled response, while the 87.5 dB sensitivity (2.83V/1m) ensures efficient power handling. A 6.2 ohm DC resistance and 0.7 mH voice coil inductance contribute to stable impedance characteristics. The chassis requires a 145.3 mm cutout and mounts with six screws on a 166.1 mm diameter circle, with an overall depth of 88.6 mm.

This SEAS Prestige series driver delivers the clarity and authority expected from a premium coaxial transducer, making it a compelling choice for discerning audio enthusiasts.
